Hello.
I have the same problem. It appears everytime when i try to install a program and this happen only to specific software firm. I tried to launch 4 or 5 different softwares the same production and i get runtime error.
win7 x64
core-i 7
nvidia geforce gt 640m
Its software for music production, mostly digital synthesizers
Issue appears only to apps which are the same production i described above
I haven't any security software, just windows protection brandmauer :)
There was issue from the beginning of using the laptop. It was win8 first i decided that the problem in OS but installing of win7 did not solve the problem
